Here’s our new Montessori-style baby room.
Mostly, she uses it for naps and as a playroom.
We use a crib mattress on the floor so (theoretically) she could go from sleeping to playing with her toys easily.
We also have a safety gate on the door so we can keep it open.
We tried to keep the room as simple as possible so that she can play safely there by herself (work in progress). So far, she is still getting used to waking up in it.
